Improvement in machines for bundling wood



UNITED STATES DARWIN A. GREENE,

PATENT OFFICE.

OF NEW YORK, N. Y.

Spocication forming part of Letters Patent No. 55,282, dated June 5,1866.

To all whom it may concern:

Be it known that I, DARWIN A. GREENE, of the city and county of NewYork, in the State of New York, have invented certain new and usefulImprovements in Machines for Bundling Wood, applicable also to otherpurposes; and I do hereby declare that the following is a full and exactdescription thereof.

My machine is adapted to be operated without the aid of power. Myimprovements relate to the mechanism through which force is applied bythe foot to compress and release the material, the mechanism by whichthe operating-lever is supported and released as the lever isalternately thrown into and out of use, and the means adapting themachine to compress material of different figures and dimensions.

I will proceed to describe the best means known to me for carrying outmy invention.

The accompanying drawings form a part of this specification andrepresent a machine constructed according to my invention, for thepurpose of tying up or bundling short pieces of wood, such as are incommon use for kindling res. I term the machine the woodbundler.77

Figure lis a vertical section on the line S S in Fig. 2. Fig. 2 is aside elevation of the main portion of the machine. Fig. 3 is a planview.

Similar letters of reference indicate like parts inV all the gures.

A is the rigid frame-work. A. is a cradle or recessed seat on the upperface of the framing, adapted to receive the kindling-wood in the obviousmanner. It is divided into two parts to allow the string to beintroduced previous to the introduction of the wood.

B is an adjustable gage, formed and mounted as represented, and adaptedto be moved backward and forward on the upper face of the frame A withinconsiderable limits after slackening the binding-screw b. The machine isnow adjusted for bundling the shortest pieces of wood. In order toadjust it for longer pieces the screw l) must be slackened. The gage Bcan then be readily moved back to the proper extent, there being alslot, b', instead of a round hole, through which the screw b passes.After finding the right position the screw b is again tightened.

O is a strap, of round iron or other suitable material, which passesover the cradle A', and is operated vertically to compress and releasethe wood. Its lower ends are connected by the stout hollow yoke C', uponwhich the strap C is adjust-able by means of jam-nuts, as indicated. Thehollow yoke O stands between rigid castings or guides, A2, which arebolted rmly upon the framing A at the top and connected rigidly togetherby a strut at the bottom. These guides have slots a, as indicated, whichfulfill the important function now to be described.

D is a lever fixed on a movable shaft, d, which stands in the slots a,and is allowed to turn and traverse up and down therein, but cannot movein any other direction.

Dl D2 are stout and short arms or knuckles, extending from the shaft din opposite directions. These arms or knuckles come between thecastingsA2 A2 anddirectly over the yoke O.

E is a short stout link, which connects the arm or knuckle D to a pin,c', fixed on the framing directly above the shaft d.

E2 is a corresponding link, which extends from the arm or knuckle D2down to a pin, e2,-

which is mounted in the hollow yoke C.

Thelinks E E2 arejointed to the arms Dl D2 by pins d d2. The stronglines and tints show the lever D in its elevated position, in whichcondition of the machine the links E and E2 are greatly deflected fromtheir perpendicular position and the yoke O and the strap C areelevated. The red lines show the lever D depressed, in which conditionof the machineY the links E E2 are drawn inward to a perpen dicularposition and they yoke C and strap O are depressed.

G is a handle or crank xed on the upright shaft g. The spring H iscoiled around and takes hold of the shaft g at one end and is fixed tothe frame A at the other. It exerts a constant strain, tending to turn'the shaft in the direction indicated by the arrow. This shaft g has aspine or longitudinal groove extending up and down a considerabledistance, as indicated by g.

I is a movable boss, fitted on the shaft g, and secured by apinchingscrew, t', which enters the spine g. On slacking this screwz'the boss I may be slipped up and down and adjusted vertically to anyextent desired.

J is a small arm extending horizontally from the boss I and connectedthereto by the pin j, so that it is free to yield or bend upward to anyextent. When the lever D has been depressed and is elevated so as tostrike the under side of the arm J the latter bends upward and allowsitto pass, immediately after which the small arm J drops again bygravity into its horizontal position and serves as a stop to support thelever D. When it is desirable to depress the lever D the shaft g isturned by operating the handle G. After the lever D has dropped past thearm J the handle Gmay be released and the shaft g allowed to return toits original position by the action ot' the spring H. The lever D maythen be depressed by the foot and held depressed while the wood which ispressed by the strap (l is tight.

K and L are stops on the upper face ol' the framing A, which limit theextent of the partial rotation of the handle G.

. A3 is a guide, represented as partially broken away in Fig. 2, whichserves to steady and support the lever D laterally.

The operation of my invention will be obvious to goodmechanics from thisdescription.

The lever D being elevated by the action of the foot or hand and allowedto rest upon the what I do claim as new, and desire to secure by LettersPatent, is a's follows l. The short links E E2, short arms D DZ, shaftd, and slots a, arranged and represented relatively to each other and tothe lever D and yoke C', or their equivalents, substantially as and forthe purpose herein specified. i

2. The hinged arm J, shaft g, spring H, and

handle G, arranged for operation in connect tion with the lever D andits connections, substantially in the manner and for the purpose hereinspecified.
